Depending on circumstances, the Embassy and USFK might decide to open all or only some of the following Evacuation Centers. US citizens should listen to AFN-K radio & television for instructions on where and when to proceed. AFKN will be the primary source of information and instruction.

Registering is a good idea.
Panicking is not.
I registered when I got here in 1997.
There are no real signs of war here yet. Just some nervousness due to the US war in Iraq.
These are two different situations NK and Iraq I mean.

Registering is one thing but taking notice of your Embassy sites and storing some food and water as advised is of the upmost importance. We and especially non-U.S. personal don't have any garrantee of a flight out of Korea.

My friend returns March 26th from Beijing. He said he would call me then. I do not have anymore information. My friend has worked internationally for 35 years, is a pretty calm-cool-and-collected type of person. My other friend and I who received the email message were a bit upset frankly, that he would send us a 2 line message with few details but someone told me today that China monitors emails. I didn't want to jeopardize his position either, so I posted my first message with a little hesitation. But if I hadn't said anything, and something happened, how would I feel? I certainly didn't mean to panic anyone. When you register, ask for the Evacuation plan. I had it emailed to me, and it is very thorough. Having that information eased my tension considerably and I feel prepared now. But I must reiterate, register at your embassy.

When the Khmer rouge occupied Phnom Penh, they allowed all foreign men with Cambodian wives to leave. Foreign women with Cambodian hubbies had to leave them behind. And brits needing assistance from the embassy were told to try at the American one. Wonderful.

You can't possibly think that there is going to be anyway out! Maybe walk and swim it down south. Wait a year for the Americans to arrive.
The mighty Canadian Navy will arrive with various battle groups and aircraft carriers to helicopter you out.! No Problem! Just just wave those maple leaf flag pins high! The North korerans accept them as dogma.

Um that's what I heard too . They tell me that he is climbing the walls just like a fly would. His little world is on on stall. He is stuck with a back log of doom and gloom data that just might become outdated before he can post it. I just can't understand what makes people like him tick. They're sick I think compared to normal people like you and I!
